The Quest for >2000 Vppss

[kevin gilmore]

the power of that part is 170mw.  so the stn0214 should work. make sure the pinout is correct.

mouser has thousands of ksc5026 in stock.

the extra diode cannot hurt. not sure what it is supposed to do.

Test build of Super-Carbon up and running to see what is what: 

 

PSU angle brackets are recycled from a previous, very tight, build, where those cutouts made perfect sense . 

Two small issues worth mentioning on amp boards. First, TTC004b and PZTA42 have opposite pinouts (ECB vs BCE) so if using TTC004b, transistor front needs to face heat sink. Second, you need to add some current limiting on the CS LEDs if you intend to use them.

Running at +/-550V. 

No listening yet; need to build a more permanent CS supply solution first and also tidy up in general.

Somewhat ironic - since I'm not in the UK, your post is showing me exactly the same amplifier picture I posted earlier :).

I see the problem though and I think it's been brough up before in this forum. I was hoping for Imgur to resolve this, but if it persists and/or spreads I might look for another image host.

Here you go. I forward the previous pic. Should be visible now.
